Pengaruh Fraksi Volume Serat Buah Lontar Terhadap Kekuatan Tarik Dan Kekuatan Impak Komposit Bermatrik Polyester

In the industrial world nowadays, natural fiber has been widely developed as an important part in the preparation of composite material. Lontar Fruit is a natural commodity enriched with fiber but still less maximally utilized. Lontar Fruit fiber is then composed with polyester matrix to be an alternative material to the preparation of polymer-based helmet and gas tube. Research attempts to examine the tensile and impact strengths of this application. In this research, therefore, polyester resin is composed with Lontar Fruit fiber and this composite is treated with alkali 5 % NaOH for 30 minutes. Preliminary test has indicated that the tensile strength of genuine single fiber (without treatment) is 33.3 N/mm2 and the maximal tensile strength of single fiber is 36.96 N/mm2 after treatment with alkali 5 % NaOH for 30 minutes. After this preliminary test, the composite is then tested by treating Lontar Fruit fiber with alkali 5 % NaOH for 30 minutes upset time against various volume fractions of Lontar Fruit fiber, respectively at 0 %, 5 %, 15 %, 25 % and 35%. It is then by the results, the favorable mechanic attributes, precisely the tensile strength and impact strength of the polyester matriculated composite with Lontar Fruit fiber as the reinforce, can be explained as follows. The best tensile strength of the composite is 47.7 MPa found at volume fraction variation of 15 %. The best impact strength of the composite is 30.1519179 J observed at volume fraction of 35 %

Ethnobotany of Lontar (Borassus flabellifer L.) in Tuamese Village, East Nusa Tenggara

Lontar is a plant that distributed in tropical areas and has beneficial values for the people in Tuamese Village, Biboki Anleu District, North Central Timor Regency. However, the information about the ethnobotany of lontar is not documented. This research aimed to determine the utilization of lontar in Tuamese Village. Data were collected using semi-structured interview techniques and field observation. The ethnobotany data were analyzed to calculate cultural significance index value. The results showed that the people in Tuamese Village who generally work as lontar farmers use stem, leaves, flowers, and fruit as building and fence materials, handicraft materials, food and drink ingredients, and firewood. Product from sap flower, namely liquid sugar, slab sugar, and traditional fermented drink (sopi) are the leading trade commodity. The utilization of lontar in Tuamese Village is grouped into seven forms of utilization with index of cultural significance 151 and classified very high. The classification means that lontar greatly affects people's lives in Tuamese Village and its use has become cultured. People's dependence on lontar is very high so the conservation effort needs to make the existence of lontar is maintained.   Keywords: index cultural significance, lontar, Tuames

Conservation Status of Lontar Palm Trees (Borassus flabellifer Linn) In Jeneponto District, South Sulawesi, Indonesia

Abstract: This study aimed to describe the botanical description, conservation status and potentials of Sulawesi native lontar palm trees (Barassus flabellifer Linn) in Jeneponto district, South Sulawesi, Indonesia. This study was extended to include a study on the community’s attitude towards preservation of lontar palm trees involving 30 people distributed over three research sites. Overall 53% of the dry-land in Jeneponto district is grown by lontar palm trees with the tree density ranging from 50 trees per ha for trees aged between 1-5 years; 37 trees per ha for trees aged between 5-10 years; and 32 trees per ha for trees aged more than 10 years. New lontar palm trees which are being managed by the local communities are planted on 27% of the land area. Tamalatea subdistrict has the largest lontar palm tree population in Jeneponto District

FOOD PRODUCT EDUCATION OF SIWALAN FRUIT (BORASSUS FLABELLIVER L.) INNOVATION IN HENDROSARI VILLAGE, MENGANTI, GRESIK

One of the areas in Gresik that has natural and environmental potential is used as a tourist spot, namely Hendrosari village. Tourist attractions in Hendrosari village called Edu Wisata Lontar Sewu provide various facilities, including restaurants and food stalls typical of Hendrosari with dishes. Palm trees are the main potential of Hendrosari village. People take advantage of the palm tree from its fruit and water. Cultivation of lontar plants as the main commodity produces siwalan (Borassus flabellifer L.). Generally, people consume siwalan fruit in fresh condition and the basic ingredients for making siwalan dawet. Fresh siwalan fruit easily rots, this causes losses for farmers and sellers of siwalan fruit. The results of previous observations obtained long shelf life of siwalan fruit products. In addition to improving the quality of siwalan fruit products, with processing efforts also increase consumer interest in buying siwalan fruit products. The variety of siwalan fruit products is also expected to increase the production value and selling value. Palm trees producing siwalan fruit in the Hendrosari village community, Menganti District are used in 2 types of products. Products sold by the public are usually in the form of fresh siwalan fruit and dawet siwalan. Community service activities through innovation in processing siwalan fruit with the aim of increasing the variety of food products and creativity of the Hendrosari village community. This activity consists of observation, licensing, training, and evaluation. The implementation of the activity was supported by the enthusiasm of the participants, the support of village officials and a group of women from Hendrosari village. The heating process aims to reduce the water content and shape the texture of food products as expected to produce snacks that are liked by everyone at various stages of age. The community needs to socialize and develop the processing of siwalan fruit into snack products from various characteristics of siwalan fruit (young, ripe, and old). Variety of snack products from siwalan fruit optimally to increase product added value, independence, community creativity and one of the choices of local tourism souvenirs

AKTIVITAS ANTIOKSIDAN DAN KARAKTERISTIK FISIK SUSU KAMBING PASTEURISASI DENGAN PENAMBAHAN BUAH LONTAR (Borassus flabellifer L.)

Palmyra fruit (Borassus flabellifer L.) contains active compounds and nutritional content that can maintain and improve the quality of processed goat milk products. The objective of this research was to analyze the antioxidant activity and physical characteristics of goat's milk pasteurized using palmyra fruit. A completely randomized design (CRD) with 5 treatments with 3 replications was used in this research with parameters of antioxidant activity, viscosity and pH. The number of panelists in organoleptic testing was 25 people. Treatments with the addition of palmyra fruit percentage of the total volume of milk made were 0%, 10%, 12%, 14%, and 16% (w/v). The addition of palmyra fruit to pasteurized goat milk had an effect (P<0.01) on antioxidant activity, viscosity, sweetness, milk taste and palmyra taste, however, it had no effect on the pH value. The use of 10% palm fruit in the processing of pasteurized goat milk will produce the best quality based on antioxidant studies and its physical characteristics. Keywords:  antioxidants, goat's milk, palmyra fruit, pasteurization, physical propertie

SELAI TALA BARAKKA SEBAGAI TEROBOSAN PENINGKATAN EKONOMI WARGA

Selama 28 hari, Aktivitas PkM ini dilaksanakan dalam beberapa tahap, diawali dengan observasi dan diakhiri dengan pemeriksaan manfaat operasional. Kegiatan ini merupakan salah satu bentuk pengabdian kepada masyarakat yang membantu perekonomian masyarakat karena dilakukan bersama dengan desa-desa yang ada di wilayah sekitar kampus. Keberhasilan dengan suatu produk diperlukan untuk meningkatkan pendapatan masyarakat. Salah satu ilustrasi pemanfaatan aset tetap (SDA) untuk lebih mengembangkan perekonomian daerah setempat adalah lompatan maju Selai Tala Barakka, seperti yang akan dianggap normal untuk lebih mengembangkan kemampuan pengganti karena aset tetap yang melimpah. Buah lontar (Borassus Flabellifer) dihasilkan di Desa Canrego, Kecamatan Polongbangkeng, Kabupaten Takalar. Selain mencegah buah aren membusuk karena menumpuk selama proses penjualan, pengolahan buah aren menjadi selai juga mencegah harga buah aren jatuh setelah panen. Pada saat panen, nilai buah sawit meningkat karena kedua faktor tersebut. Pengawetan selai buah sawit dapat diperlambat. Selai yang dihasilkan dapat digunakan untuk mengisi kue, roti, dan kue kering. Produksi Selai Tala Barakka telah berhasil meningkatkan perekonomian warga melalui eksperimen
